London (CNN)British police have opened an investigation into allegations of anti-Semitic hate crimes within the Labour Party.
Labour anti-Semitism allegations to be probed by police
The move, which was announced Friday, comes after a dossier of information detailing 45 cases of anti-Semitism was handed over to police by London-based radio station LBC last month.
A spokesman for the Metropolitan Police confirmed that a criminal investigation had been started to examine a number of allegations within the document.
Met Police Commissioner Cressida Dick told the BBC Friday that the Labour Party itself was not under investigation but said the allegations would be examined.
"We are not going to investigate the Labour Party. We would always want institutions and political parties and similar to be able to regulate themselves," she told BBC Radio 4's Today program.
"However, if somebody passes us material which they say amounts to a crime we have a duty to look at that and not just dismiss it.
"We have been assessing some material that was passed to me, in a radio studio of all things, about two months ago and we are now investigating some of that material because it appears there may have been crime committed. We are liaising immediately with the Crown Prosecution Service and I hope we will be able to clear that up very quickly."
